Thulium Hydride (TmH2~3)-Powder
Characteristic
Thulium hydride is a compound of hydrogen and thulium. It is considered to be a part of the class of rare-earth metal hydrides. Metal hydrides are very attractive and important materials in the hydrogen storage material field. Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Thulium is relatively stable in air; thulium oxide is light green crystal. Silver-white metal, soft, with high vapor pressure at melting point.

Application
Thulium is mainly used in the production of additives for neodymium iron boron alloys, giant magnetostrictive materials, magneto optical storage materials and nonferrous metal alloy casting. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices, and in some solid-state lasers. It has no significant biological role and is not particularly toxic.
Package
Vacuum pumping and argon protection, 500g or 1000g / bottle.
